Suppress the WARN logs when clearing Select List, Radio, Checkbox fields' value using .setFormValue("")

As a Jira Administrator

I want the WARN logs thrown to be suppressed when clearing Select List, Radio, Checkbox fields' value using .setFormValue("")
Example: Option with value '' is not valid for field: customfield_11701

So that it will reduce flooding the log files with invalid warnings, as the values do get cleared as expected.

Workaround:
Use .setFormValue(null) instead when clearing Select List, Radio, Checkbox fields' value

FROM 6.55.0 onwards: 

When using .setFormValue("") the warning "Option with value '' is not valid for field" is still shown in the logs. 

When using .setFormValue(null) the warning "No option found for customfield_10701 with value -1" is shown in the logs
